It seems no observer further south than the eminent observers in
Australia have stepped forward to track USA 129 rocket after Jan.20.

So, decay predictions are rather uncertain. The latest elset I saw
agrees well with the other 10 after Jan.12.

They indicate decay around Jan.29-30. 

The orbit plane will pass in shadow NB at 35S around 22.15 local time,
around 21.30 local time NB at 50N (around 10.00 SB in daylight)

Here are SatEvo evolutions for the last day (?)
